Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Couplings for rigidly connecting two coaxial shafts or other movable machine elements > for attachment of a member on a shaft or on a shaft-end > with clamping hub; with hub and longitudinal key > with radial clamping due to axial loading of at least one pair of conical surfaces

CPC:

Couplings for rigidly connecting two coaxial shafts or other movable machine elements (attachment of wheels to axles for railway carriages B60B; for attachment of cranks to their shafts F16C3/10) > for attachment of a member on a shaft or on a shaft-end (attachment of marine propellers on shafts B63H23/34) > with clamping hub; with hub and longitudinal key > with radial clamping due to axial loading of at least one pair of conical surfaces

Of 5 combined children, 3 exist in both systems.

2 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

1 shared codes have differing titles between IPC and CPC.
